| 摘 要： | 由于环境等因素的影响, 研制阶段制定的初始备件方案在使用初期常常无法满足装备保障要求. 针对该现状, 以装备的初始备件方案为先验信息, 结合其使用阶段的备件消耗特性, 利用Bayes方法, 对其工作失效率进行了估计, 并在此基础上, 提出了装备使用初期的备件配置数量调整方法. 仿真结果表明利用该方法调整后的备件数量能够满足 装备的保障要求, 与传统方法相比, 本方法具有较高的估计精度和稳健性, 能够更加合理配置备件方案.

| Abstract: | Because of the environment and so on, the spare number of initial spare scheme can't meet the equipment support requirement when the equipments are in incipient operation. Aim at these statuses, the initial spare scheme was used as prior information. And then the regulate method of spare in incipient operation was proposed based on the Bayes method. Finally, the simulation example shows that the method proposed is feasibility. Comparing with classical method, the method proposed can improve the accuracy of estimation and has good steadiness. So the more rational spare scheme can be formed. |
